Building a home is such an exciting journey! With a budget of $130,000, it's great that you're doing your homework on builders. I've heard decent things about Fairmount and AV Jennings; they usually have good options for smaller blocks. Rosedale is another one to check out, but I’d dig deeper into Statesman Homes and Format too—might find some hidden gems! Just make sure to ask about any extras that could add up. If you need some outdoor ideas later, you might want to check out https://cosydeals.com.au/catalogs/wall-mounted-pergola-gazebo for a nice touch. It can be useful for choosing a wall mounted pergola gazebo. Good luck with it all!
